Abstract
A device for whipping cream or egg whites having a cup-shaped cylindrical housing with a preformed bottom, a cap releasably locking the open top, a perforated plunger piston connected to one end of the piston rod and movable within the housing, the piston rod being movable through the cap and formed with a handle at its opposite end, one of two perforated plates spaced from the plunger piston on the piston rod. The perforated disc is biased by a spiral coil spring from the plunger and may be further biased from a second perforated disc. When the discs and plunger are compressed together, any product between them is squeezed out through their holes.
Claims17
A device for whipping a product, comprising:
- a housing to contain said product;
- means for whipping said product in said housing and including a plunger piston having an axis and a plunger disc perpendicular to said axis, said plunger disc having a plurality of holes passing therethrough;
- at least one plate having a plurality of holes and being axially spaced from said plunger disc and axially movable relative to the latter;
- and
- means for biasing said plate relative to said plunger disc, said biasing means being arranged between said plate and said plunger disc, at least one of said plate and said plunger disc having an indentation formed to accomodate said biasing means in a fully compressed condition so that said plate and said plunger disc are in contact with each other when said biasing means is in said fully compressed condition to thereby effect a full explusion of the whipped product from between said plate and said plunger disc.
